Protosciences are fields of study that existed before the modern scientific method was established[note 1] before developing into proper science. They were often concerned as much with occultism or religion as with natural phenomena. Continuing to hold belief in a protoscience that has been discredited in favor of a modern scientific field is considered pseudoscience. In a broader sense, much of science could also fall under the term "protoscience". If a field of study is consistent with existing science, but has not yet been tested rigorously by the scientific method, because it is still in its formative years, then that protoscience (read: not-yet-science) is to be distinguished from pseudoscience (read: never-science). Technically speaking, all science could be a protoscience: you never know if tomorrow, something new will be found which utterly shakes the foundations of science and creates a paradigm shift (kind of like what radium did a century ago).
